McDonald's Time Line Case Study McDonald's is an American fast food company, founded in 1940 as a restaurant operated by Richard and Maurice McDonald, in San Bernardino, California, United States. They rechristened their business as a hamburger stand, and later turned the company into a franchise, with the Golden Arches logo being introduced in 1953 at a location in Phoenix, Arizona. The manager is interested in identifying the correct way to measure important variables describing McDonald's operations. When we assign this case, the manager is primarily evaluated on his effort in identifying factors that are important for the organization to determine. This is an easy case to do quickly, but can easily become challenging. The manager should not only be required to identify what is to be measured, but also how it is measure, potential sources of bias and also identify the level of measurement. To accomplish this mission, the manager selected a simple random sample of customers and asked them about the time they received their orders. The collected data are expressed in the following frequency table: Customer waiting time(seconds) customers # of 0-30 2 31-60 19 61-90 47 91 120 54 121-150 61 151-180 46 181-210 51 211-240 241-270 42 40 For the homework assignment, we look for a well-organized and neatly presented written report including narrative that explains the graphs along with conclusions reached from analyzing the data. The central issue of this case involves the use of graphical descriptive statistical techniques. QIICLO 1] (5 marks) Organize the time data into a useable histogram and check how many customers receive their order in 90 seconds or less? Does it look good? Q2|CLO1] (5 marks) If it doesn't look good, then this should lead to a discussion of what is important to measure. Therefore, distinguish between standing in line to place and order and, once it is placed waiting to receive it. That is check to see if service time as measured is different depending on the meal of Breakfast, Lunch and Dinner, where the collected data are shown below:
